Brief summary
The purpose of this study is to comparing the effects of different double-lumen endotracheal tube's bending type in tracheal intubation.
Detailed description
Intubation with the double-lumen endotracheal tube (DLT) remains a great challenge for anesthesiologists. Although new upper airway devices, such as GlideScope(R) videolaryngoscope, had been developed for facilitating airway management, the larger size and the complexity of DLT than single-lumen tube (SLT) makes the difficulties for DLT intubation. Therefore, the investigators designed this study to investigate the effects of different bending type of DLT in tracheal intubation.
Interventions
PROCEDUREthe DLT bending to the right
bending the bronchial lumen of DLT 60\ 90 degrees in the same side with the tracheal lumen
PROCEDUREthe DLT bending to the left
bending the bronchial lumen of DLT 60\ 90 degree opposed to the tracheal lumen
